Starting in 2002, the Office of the United
Nations High Commissioner for Refugees (UNHCR) has facilitated one of the
largest and most rapidly organised voluntary repatriation movements of
refugees in modern history (1) (UNHCR 2006a: 144). To date, UNHCR estimates
to have assisted 3.7 million Afghan refugees to return to Afghanistan,
2.9 million from Pakistan, 800,000 from Iran, and 14,000 from non-neighbouring
states (UNHCR 2007: 3).
